WIRE MESH FOR CYCLE-SEATS.

SPECIFICATION forming part of Letters ram No. 656,231, dated August21,1900.

Application filed December 2 ,1899. Serial Harness. (No model.) i

To all whom it may concern-.1

Be it known that I, ALFRED EDMUND WALE, a subject of the Queen of GreatBritain, residing at Dunstan House, Elmdon, near Birmingham, England,have. invented certain new and useful Improvements in Woven- Wire Meshfor Cycle-Saddles, Seats, and other Articles, of which the following isa specification.

My invention has for its object improvements in woven-wire mesh forcycle-saddles, seats, and other articles, by which I produce or weave afabric of greater fineness and smoothness of surface than hashithertobeen possible and which will be found especially siliitable forthe covers or seats of cycle-sadd es. s

In order'that my invention may be more clearly understood and easilycarried into practical effect, I have appended hereunto drawings, uponwhich I have shown several examples of my woven-wire mesh.

Figure 1 is a plan view showing a portion of my new fabric and aportionof the founda-' tion or primary fabric. Fig. 2 isaplanview showing aportion of a finer-woven fabric and a portion of the primary orfoundation fab-' ric. Fig. 3 is an inverted plan view of Fig. 1, showingan additional mesh interwoven on the under side. ing another form of myfabric with a strengthening fabric woven on the under side. Fig. 5 is aninverted plan view of Fig. 1, showing the strengthening under fabricengaging with every transverse coil.

In carrying my invention into practice I first weave the foundation orprimary fabric A of sufficient fineness from two separate and similarsets of helices a and a which are interwoven with one another at-rightangles and in the same horizontal plane. I then take another helix 1) ofthe same diameter, pitch,

and thickness of wire and engage it with two of the longitudinal helicesa, but not with the transverse helices a. The helix 1), however, lieswithin their convolutions, as clearly shown at Fig. 1, and has its upperand lower surfaces immediately below the upper and lower surfaces of thetransverse helices 00 I now take another similar helix b and engage itwith one of the two longitudinal helices ct already engaged with thehelix b and also Fig. 4 is a plan view show- I with the nextlongitudinal helix'a and with the helix 1), thus engagingtwo of thehelices a of the foundation fabric A in the same manneras with the'helixb. This process is repeated until the full Width of the primary orfoundation fabric A has been so treated and convertedinto thefiner-surface fabric B,

or I also obtain a finer-surface fabric by Weaving the double-wovenfabric D upon the upper surface of the cross-woven primary or foundationfabric A in the following manner, as shown at Fig. 2: I first taketheadditional helix (1, of the same diameter and pitch and preferably ofthe same thickness of wire, and interweave" it with one of thelongitudinal helices a of the primary or foundation fabric. I then takeanother or secondhelix (1 of the same diameter and pitch and intercoilit with the helix d and also with the same longitudinal helix a. Thethird additional helix d is then interwoven with the next longitudinalhelix a of the primary or founda tion fabric A'and also with the helicesd and 61 I then take the fourth additional helix (1 and intercoil itwith the same longitudinal helix a as the additional helix d and alsowith the additional helices d and d ,as clearly shown at Fig. 2. Thisprocess is repeated until the desired width of fabric is obtained byadding two additional helices to each longitudinal helix of the primaryor foundation fabric A, thereby producing the fabric D, which has a fineupper surface; ,but the additional helices 61, d 0F, and d are not inthe same horizontal plane as the helices a of the cross-woven primaryfabric or foundation fabric A.

In order to obtain the necessary strength for cycle-saddles infine-woven wire fabrics, as above described, I weave another fabric orfabrics upon the lower surface of the cross woven foundation or primaryfabric A in the following manner.

In the case of the fine-upper-surface fabric D, as shown at Fig. 2, Iprefer to interweave upon the lower surfaces of the helices a of thefoundation or primary fabric A a single longitudinally woven fabric (nota crosswoven) in such a manner that each convolution of each helixengages with the convolutions of the corresponding longitudinal helix a.Another fabric of a similar.nature is then woven upon the under surfaceof this single longitudinal woven fabric, or I may use compound helicesformed of two or more helices instead of single helices.

In the case of the fabric B, woven according to the method of obtaininga fine upper surface, as shown at Fig. 1, I may interweave upon thelower surface of the primary or foundation fabric A another fabric E,the helices e of which engage with one or two of the longitudinalhelices a of the fabric A and also with the helices of the fabric 13, asclearly shown at Fig. 3, or with the helices of the fabric Bonly 3 but Iprefer to weave the strengthening fabric F on the under side of theprimary or foundation fabric A, and I employ helices f of the samediameter and pitch as the helices a, but of the opposite hand-that is tosay, if the helices a of the primary or foundation fabric A areleft-hand pitch the helices f of the under strengthening fabric F wouldbe right-hand pitch, as shown at Fig. 4, and preferably of a thickergage of wire. In this case the helices f of the strengthening fabricengage only with each alternate transverse helix a of the primary orfoundation fabric A. The strengthening fabric F may consist of singlehelices or compound helices formed of two or more helices.

In some cases when using the strengthening or under fabric F of aright-hand pitch in conjunction with the primary or foundation fabric Aof a left-hand pitch each convolution of each helix f may engage witheach transverse coil a of the foundation or primary fabric, as clearlyshown at Fig. 5.

What I claim is-- 1. The new woven-wire mesh or fabric for cycle-saddlesseats and other articles consisting of the combination with a primary orordinary cross-woven wire fabric of longitudinally-woven helices ofeither right or left hand convolutious engaging and interlocking withthe helices of the primary fabric either on one or both sides of theprimary fabric substantially as herein set forth.

2. The woven-wire mesh or fabric for cyclesaddles or the like,comprising a primary cross-woven fabric A of helices and a supplementalfabric one longitudinal helix of one fabric engaging two longitudinalhelices of the other fabric, substantially as described.

3. The woven-wire mesh or fabric B for cycle-saddles seats and otherarticles composed of helices b b in combination with the primary fabricA each of the helices b and I) being caused to engage with two of thelongitudinal helices a of the cross-woven primary or foundation fabric Athus producing one new fine strong fabric in the manner and for thepurpose substantially as herein set forth.

4. In combination with the cross-woven primary fabric A, a supplementalfabric engaging the same con sisting of longitudinal helices engaginglongitudinal helices of the primary fabric, and a series of additionalhelices interwoven with the primary fabric on the under side of thesame, substantially as described.

5. In combination with the primary crosswoven fabric A, a supplementalfabric comprising longitudinal helices engaging with the longitudinalhelices of the primary fabric and an additional fabric interwoven on theunder side of the primary fabric, said additional fabric having itshelices of different hand from those of the primary fabric and engagingalso with transverse helices of the primary fabric.

6. In combination with the primary crosswoven fabric A, a supplementalfabric comprising longitudinal helices engaging with the longitudinalhelices of the primary fabric and an additional fabric interwoven on theunder side of the primary fabric, said additional fabric having itshelices of different hand from those of the primary fabric and engagingalso with each alternate transverse helix of the primary fabric.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

ALFRED EDMUND \VALE.
